China EVOH High-Barrier Material for Professional Packaging - Top Suppliers & Factory Solutions
Performance Features of SVW™ EW-2901S in Professional Applications
1. Superior Material Safety and Molecular Purity
EVOH is composed exclusively of carbon, hydrogen, and oxygen, with no added plasticizers during polymerization or processing. Its highly crystalline molecular structure ensures exceptional stability and minimizes the risk of substance migration, making it suitable for direct contact with pharmaceuticals and active cosmetic ingredients.
2. Global Regulatory Compliance for Safe Use
Medical- and food-grade EVOH fully complies with major international regulations, including:
- EU: ECHA Chemical Classification & Labelling (C&L) inventory and EU food contact standards
- China: GB 4806.7-2025 and GB/T 28803.1—2025 “Dynamic Risk Assessment” framework
- USA: FDA 21 CFR 177.1360 and USP Class VI biological testing
This comprehensive compliance allows EVOH-based packaging to be safely used in global healthcare and personal care markets.
3. Exceptional Barrier and Chemical Stability
EVOH offers industry-leading oxygen barrier performance and remarkable chemical resistance. These properties ensure that both medical and cosmetic formulations maintain efficacy, integrity, and fragrance stability throughout sterilization, storage, and use.
4. Tunable Material Design for Diverse Packaging Formats
EVOH’s material properties can be precisely adjusted to meet different packaging requirements:
- High-ethylene grades (~44%): Improved melt flow for thin-wall bottles, tubes, and pouches
- High vinyl alcohol grades (~32 mol%): Maximum barrier performance for oxygen-sensitive formulations
This versatility allows EVOH to be used in bottles, jars, tubes, pouches, and airless systems, providing reliable performance for both pharmaceutical and cosmetic products.
